Trans-Tasman catering and cleaning firm Spotless has admitted to a huge data breach in which hackers may have obtained past and present staff members’ passport and IRD numbers, amongst other personal information.

I was wondering as I don't think I have ever had to give an employer my passport number, are some companies requiring this routinely ?
I expect as the data breach got this it probably also got bank account numbers for pay as well, if they got IRD numbers.
